Tired of letting Parallels Desktop 7 hog the spotlight for the last week or so, VMware is nipping at their virtualization heels with the release of Fusion 4 -- turbocharged and refined from the inside out for the ultimate Windows on Mac experience, and available for a promotional price for a limited time only.

If you’re a Mac user who needs to occasionally access Windows or Linux, chances are good that you’ve turned to Parallels Desktop, the leading virtualization software on Apple’s platform. If you’ve also already upgraded to OS X Lion, you’re in for a treat, because Parallels Desktop 7 for Mac has finally arrived with full support for the big cat.

If your workday consists of running any kind of Windows application or even multiple instances of OS X Lion, you’re no doubt excited about Parallels Desktop 7, the latest version of the virtualization software arriving September 6, complete with OS X Lion support and a new mobile app.
